Improvement in cultivators



UNITED STATES PATENT OFFICE.

GEALY BILLUPS, OF NORFOLK, VIRGINIA.

IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 135,070, dated January21, 1873.

To all whom it may concern:

Be it known that I, OEALY BILLUPs, of Norfolk, in the county of Norfolkand State of Virginia, have invented certain Improvements inCultivators, of which the following is a specification:

The invention relates to cultivator-plows, upon which are made certainimprovements that will be first fully described in connection with allthat is necessary to a full understanding thereof, and then clearlypointed out in the claims.

Figure 1 is a side elevation. Fig. 2 is a perspective view of the wedge,and Fig. 3 is a detail view of the sweeps.

In the drawing, A represents the beam; B B, the handles and O, thestandard, the latter being provided in front with wings, to whichmold-boards or shovels are to be attached in the usual manner, andhaving made transversely through it, in rear of the wings, perforationsc c, with an intermediate slot, 0, by means of which and clamp-bolt aready means is provided for the attachment to and adjustment upon thestandards of sweeps D. These sweeps have stout shanks a, formed at anobtuse angle at their inner ends, and are perforated at d, and providedwith a stud, d. The two sweeps are placed opposite to the same pair ofholes 0 0, into the first of which is entered the stud of each wing,while a clamp-screw or bolt passes through the other hole 0, and holdsthe sweeps securely to the standard. The object of the slot in thestandard is to permit the adjustment of the sweeps to a greater anglevertically, and this is done by placing the studs thereof in the slotwhile the clampscrew remains in the front hole of the lower two. E is aslotted wedge working over a screw, F, and having the edge flanges e cplaced at right angles thereto, and employed to embrace the beam andupper surface of standard, thus preventinglateral displacement ofeither. By loosening the nut that holds the screw F the wedge may bemoved in either direction, according to the pitch desired. The handles BB have their ends I) b clamped to standard by a screw passing through itabout midway between the bottom and top of standard. This brings thehandles in an oblique plane, corresponding nearly or quite with theaverage pitch or inclination of plow-point, whereby they form a perfectbrace to the rear end of the beam, and give a complete leverage controlof the plow.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. A slotted wedge,'E, having the flangese e and e 6 upon its opposite sides, applicable as and for the purposedescribed.

2. A cultivator-plow sweep having the shank a with hole d and stud d,constructed substantially as and for the purpose described.

3. The standard 0, having parallel pairs of holes 0 c and intermediateslots 0, as described, to enable the sweeps to be either raised ordepressed, and also allow their pitch to be changed. a
